Fluorite with Quartz

Elongated cubic Fluorite crystals, all roughly aligned with one corner pointing vertically, form a gentle mound of stepped, semi-parallel crystals.  The Fluorite is almost completely coated by a sub-mm thick, yet pervasive, opaque film of micro-sucrosic Quartz crystals, masking the Fluorite in a creamy-white layer occasionally tinged burnt tan.  The colour of the Fluorite can be best seen on the specimen’s base , this being an almost colourless pale yellowish-green.  From Erika mine, Säulnhof, Stulln, in the Wölsendorf Fluorite Mining District of Bavaria, Germany.
